Introduction

The 326X Series Modem supports an asynchronous AT Automatic Calling Interface (Auto-Call Unit or ACU), that is compatible with the industry-standardAT command set.

AT commands provide a standard modem communications interface, allowing you to configure and operate a modem from an asynchronous terminal or PC keyboard. AT commands define how the modem is configured, how it makes calls, and the test operations the modem performs. In addition to supporting industry standard AT commands, Telenetics has developed an enhanced AT command set for the modem.

• Industry-Standard AT Command Set—AT and AT&

AT ACU

Using the

These commands, called action AT commands, are intended for immediate modem action and let you perform day-to-day operations, such as dialing and storing numbers from your asynchronous DTE. TheseAT commands do not cross-reference to the modem front panel.

• Telenetics Enhanced AT Command Set—AT*

Using these Telenetics AT extensions, you can also configure most modem options. These AT commands, called configuration AT commands, control the same options as in your modem’s front panel menu tree.

This chapter discusses:

•The AT Command Set

•Using AT commands

•Action AT commands

•S-Registers

For an alphabetized quick-reference list of AT commands, corresponding front panel options, and command functions, see Appendix A.

The 326X Series Modem supports two additional ACUs:

•V.25bis ACU, for asynchronous and synchronous applications

•LPDA2 ACU, for synchronous applications

For details, refer to Chapter 3 in the 326X Series Modem Reference Guide.

If you are using communications software, you normally do not use the AT command set directly. Your communications software will do this for you.
